Preferably, the four magnetic poles comprise two positive and two negative poles, the two positive poles defining opposite diagonal vertices and the two negative poles defining opposite diagonal vertices of the quadrilateral shape. Each of the magnetic poles are magnetically attracted to the two oppositely charged poles and magnetically repelled by the like charged poles. Containment means hold the magnetic poles of the magnetic bodies in the above described configuration. Attached to the containment means are three important and function-altering components of the technology. Flux return ring (16a) is attached to the bottom of the described four electromagnetic heads; this ring enhances the flux field and controls unwanted stray induction currents as well as stray flux from the opposite pole. A flux focusing ring (16) is positioned around the flux heads adjacent to the insulated wire coils. Attachment means hold the focusing ring in proper location for maximum benefit. Attached to the flux focusing ring are focusing coils (18a, 20a, 22a, and 24a). These focusing coils are attached to the flux focusing ring in proximity to a head of like charge and at 45 degree to 90 degree angle to the long axis of the primary flux pole. In this position, the flux focusing coils along with the focusing ring, the flux return ring and the new iron core of this invention make the gradient steeper, increase the field strength and decrease heating and stray high currents. The flux return ring and the flux focusing ring are grounded to reduce stray induction currents and the variables that they add to the therapeutic magnetic field.

Abstract: PURPOSE: A method for making a capacitor of a semiconductor device is provided to prevent the occurrence of bridges between adjacent storage node electrodes due to the abnormal growth of a polysilicon layer. CONSTITUTION: A making method for a capacitor(20) begins with forming of an interlayer dielectric layer(12) on a semiconductor substrate(11). The dielectric layer(12) is then partially etched to form contact holes(13) exposing some portions of the substrate(11). Next, the first polysilicon layer(14) is deposited on the dielectric layer(12) with a thickness enough to fill the contact holes(13). The first polysilicon layer(14) is then patterned together with a sacrificial oxide layer formed thereon. Thereafter, the second polysilicon layer is deposited and etched, thereby forming sidewall spacers(16a). In particular, the etch of the second polysilicon layer is done by a plasma etching process employing chlorine gas or sulfur fluorine gas, so that the abnormal growth of the polysilicon layer is prevented. The sacrificial oxide layer is then removed, and therefore storage node electrodes(17) are obtained. Next, a dielectric layer(18) and the third polysilicon layer(19) for a plate electrode are successively deposited.

Abstract: PURPOSE: A device is provided to achieve an improved power durability of a surface acoustic filter while preventing change of impedance of the filter. CONSTITUTION: A device comprises a substrate; and surface acoustic wave filters(40) disposed onto the substrate as being spaced apart from each other. The acoustic wave filters are electrically connected in parallel, and have electrode fingers of which overlap length is reduced for power distribution. The surface acoustic wave filters have reflectors(43) arranged at left and right sides of an input converter(41), and reflectors(47) arranged at left and right sides of an output converter(45). The input converter includes a center converter(141), and lateral converters(241) arranged at both sides of the center converter. The input converters of each of the surface acoustic wave filter are connected to a common input terminal, and the output converters are connected to a common output terminal.
